Katy Perry‘s doing her best get-out-the vote effort: At a rally for President Barack Obama, she wore a tight white dress imprinted like a ballot, and a square box on her right hip filled in the names of Obama and Joe Biden.

Perry gave a free concert at a park in a historically minority neighborhood just northwest of downtown Las Vegas to screaming fans at about 9 p.m., the same time Air Force One landed at McCarran International Airport across town.

Obama later told the crowd, “I believe in you. I need you to keep believing in me.”

The Las Vegas campaign event drew more than 10,000 people, according to fire officials and organizers, with long lines still on sidewalks during Perry’s 30-minute performance before Obama arrived.

The singer opened with a rendition of Al Green’s soul hit, “Let’s Stay Together,” and played five songs, including “Teenage Dream,” before ending with a thumping bass drum version of “Firework.”

Perry, who recently also played a free concert at an Obama event in Los Angeles, paused before the last song Wednesday to exhort people in the Las Vegas crowd to vote early.

“Don’t wait. Go tomorrow,” she said. “How many of you are 18 here? It’s going to be your first time, right?”

Christian Bale may not save lives in reality, but the actor definitely tries to make a difference in the lives of his fans.

The Dark Knight Rises star flew 4-year-old leukemia patient Jayden Barber and his family out to California for lunch date at Disneyland’s Club 33 earlier this week.

“Finally can share!!! Christian sent us to LA and we had lunch at Disney club 33 on wed,” Barber’s mother wrote with a picture of the two on her Lighting the Batsignal for Jayden Facebook page. “He and his family were so awesome and down to earth!!!”

Charlene Barber continued by sharing her family’s experience with Bale at the Anaheim theme park, “The entire interaction was like old friends having lunch. Jayden did not get star struck but was well aware of who we were with!”

“They talked movies and super Heros an he was genuinely happy to hear about everything Jayden wanted to tell him. Christian, his wife and daughter are three of the most beautiful people we have ever met! Christian made these arrangements for us personally and ensured we were treated like royalty. I don’t have even one negative thing to say about them. I can tell you that they were just as impressed w Jayden as Jayden was w them :)”

According to WYTV in Ohio, Barber was undergoing chemotherapy for bone cancer for two years before it turned into MDS leukemia last year. Jayden is now in remission.
